Test knit.

I modified this pretty heavily as you can see by dropping all kinds of stitches that weren’t specified in the pattern.

Warning to those who want to drop stitches at random: It will change the size and possibly distort the shape (depending on where you drop) so be careful.

I’ve got some fit issues in the armpit as you can see in the first photo but it’s still wearable I think. It’s a Dolman sleeve! Sort of.

As others have mentioned I’d say this pattern is for those who’ve knit a few sweaters, not because the knitting is inherently difficult but there is quite a bit going on in the pattern and I’d imagine it would not be easy to follow for a first-time sweater knitter.
